Proximal end catheter coupling hub



FIG. 1 is a perspective view of a proximal end catheter coupling hub embodying the inventive design;

FIG. 2 is a front elevation view of the proximal end catheter coupling hub of FIG. 1;

FIG. 3 is a top plan view of the proximal end catheter coupling hub of FIG. 2;

FIG. 4 is a rear elevation view of the proximal end catheter coupling hub of FIG. 2;

FIG. 5 is a bottom plan view of the a proximal end catheter coupling hub of FIG. 2;

FIG. 6 is a right elevation side view of the proximal end catheter coupling hub of FIG. 2; and,

FIG. 7 is a left elevation side view of the proximal end catheter coupling hub of FIG. 2.

The broken line showing of the hand, tubes, sutures and bandage in FIG. 1 is for illustrative purposes only and forms no part of the claimed design. 

What is claimed is the ornamental design for a proximal end catheter coupling hub, as shown and described.
